Eye-Fi camera cards

A year or so ago I purchased a card for my digital camera from http://www.eye.fi/.  This simple little card makes me happy at least once a week.  It's genius: it is wifi aware.  Which means that once you take a picture, it tries to connect to the internet and upload the new pictures.  You can have it save just to your computer, or automatically upload to Flckr, Picasa, or a number of other sites.

Here is my happy use case.  Often while at work, I'll get an email that looks like this:

Which means that the family at home has been taking pictures, and my day is interrupted by a cute and often candid update of what my fantastic family is up to today.  

The new cards will also upload videos, which means that I rarely, if ever take my card out of my camera anymore.  

Overall, this is one technical gadget that makes my life easier and has extremely low friction.  Exactly what a quality item should be.
